RegisterHotKey()

Mnemonics and hot keys are not the smae thing. You need to call RegisterHotKey() if you want ALT+1 to be seen by your applicaton even if it does not have focus.

Thanks! So if I don't want ALT+1 to be used/see by my app when it does not have the focus what do I need to do? Should I be using an Accelerator Table? I thought accelerator tables were only for shorcut keys (keys that would correspond to a menu option (CTRL+O for Open) can they also be used for things other than menu options? I am confused by the terms shortcut keys, accelerators and Mnenmonics. Are they the same thing or are there differences?
Thanks for your help! Smile | :)

An accelerator is a keystroke or combination of keystrokes that generates a WM_COMMAND or WM_SYSCOMMAND message. Although accelerators typically generate commands that exist as menu items, they can also generate commands that have no equivalent menu items.

A mnemonic is a selected letter or digit in the label of a button or in the text of a static control. The system moves the input focus to the control associated with the mnemonic whenever the user either presses the key that corresponds to the mnemonic or presses this key and the ALT key in combination. Mnemonics provide a quick way for the user to move to a specified control by using the keyboard.

MFC ActiveX Control Array Transfer

Hi,

I want to transfer an array from an ActiveX Control using a method. I have figured out that I have to set up a UDT, but I'm unsure on how to do this. I am writing the ActiveX in MFC C++ .NET

If I have the following struct:

typedef struct testArgs {
int test1;
int test2;
BYTE * test3; // This is a array
} test;

How can I get this to so that it is accessible in say Visual Basic .NET.

Any help would be greatly appreciated.

Setting an integer to the Array number as opposed to the array value

Hi,

I'm currently doing a university project for a resistor value selector program.

For this project, I have the program load in a series of calculated values into an array's elements. I now require my program to find the element of the array that has the smallest value and set an integer 'a' with the number of the element as opposed to the value it holds i.e.

SEL[0] = 2.3
SEL[1] = 3.4
SEL[2] = 0.3

I need the integer a to equal 2 not 0.3.

Any help would be great thanks!

This is a logical question!!! U can easily find better logic than this!!!

int MinValue = SEL[0];
int ArrayVal = 0;

for (int i= 0; i < ARRAY_SIZE; i++)
{
if ( SEL[i] < MinValue )
{
ArrayVal = i;
}
}

Sort the array, then set a to 0.

Question about icons

Hi,

I want to insert an icon into my application's resource, but every way I do it, it comes out ugly.

I extracted an icon from shell32.dll, and tried to import it into the icon editor of VC++ .NET 2003. However, the 32x32 32bit icon has an ugly black mask around it. If I open the same icon in Axialis IconWorkshop, the icon looks fine.

How would I normally get a 32bit icon in my resource, without having VC++ messing it up?

You can insert any icon you like into your resource file, but don't try to open or edit it inside Visual Studio because it will screw it up. The icon editor only supports up to 256 colour icons. The icon will still work correctly in your application if you don't edit it inside Visual Studio.

You need to write an image editor as an embedded control in IE, then you need to write a web service to copy the images down to the editor, and to send them back up to save at the server.

A lot of work.

When you populate the control with the names of files, are you using FindFirstFile()?

Download the source code if it is available.

If its a java program, there are many decompilers that generates the java code out of the byte code.

Load/save multiple rft strings in one file

Hi!

What I want to do is to save many (70k+) rtf strings into one file. The problem is that rtf uses \r\n, which causes that only a part of a string is read from the file when I try to load it.
I'd like to avoid reading/writing fixed length block for each string since their length varies from 50 to 1200 characters (plain text, make it x3 in rtf).

If anybody has a way of doing it without saving as text, reading line-by-line and checking whenever it is a predefined separator I'd really appreciate it.
No .Net please (I’m already feeling bad about using MFC and I think I’ll have to send some angry emails to billg@microsoft.com just to feel better).

this:

CStdioFileEx input; //CStdioFile-derived class for Unicode/Multibyte
CStringW theString, temp;

input.open (_T("somefile.txt"),CFile::modeRead);
input.ReadString(temp);
while(theString != definedSeparator)
{
theString.Append(temp);
input.ReadString(temp);
}

just looks bad.
